From C# to
enterprise systems
I started as a software developer in 2018 — building an e-commerce platform and a task-management system while finishing my BS in Information Technology (graduated with a 3.82/4.0 GPA). From there I moved into hospital accounting systems, warehouse inventory platforms, and blood-donation management software — production systems built for real operations teams, not classroom projects.
Since 2022 I've been a senior developer on a real estate technology platform used daily by 500+ licensed agents in Singapore — architecting a WhatsApp Business automation hub, a multi-tenant CMS, and the REST APIs behind a companion mobile app and ERP. That work earned me Developer of the Year in 2023 and Best Team Leader in 2024.
Alongside that full-time role, I still take on freelance projects through Upwork and Fiverr — CRM, ERP, e-commerce, and automation builds for clients across real estate, logistics, hospitality, and FinTech. If you need a senior .NET/React developer who can own a project end-to-end, that's what I do outside the day job too.
Quality over speed
I'd rather take an extra day to get it right than ship something that breaks in production. Clean code, tested, documented.
Transparent communication
You always know where the project stands. Weekly updates, working demos at every milestone, no surprises.
Deadlines are commitments
If I say it ships Friday, it ships Friday. I plan conservatively and flag risks early — not the night before.
Always learning
The .NET and React ecosystems move fast. I invest time every week in learning — new patterns, new tools, new approaches.
